The problem is deeper. We make decision based on current state (is it online
now?) that effect changes we would do in the future (don't enqueue the
offline->online event). Filtering needs to be done when the actual decisions
are made not when the event is getting enqueued.
I think in the long run we should be moving towards external events being
queued (link state changes) but internal changes be immediate (object state
changes).
